INSULATING LATH FOR BUILDING AND LIKE STRUCTURES In the building of a house or like structure, it is common practice to install insulation (such as rock wool, aluminum foil, etc.) between the studs of the wall and the beams of the floor and finished. This involves two separate operations.

In accordance with the present invention, metallic reflective heat insulation is combined with. a lathing material in a building unit so as to reduce the number of operations heretofore required. By the use of this invention, it is possible to obtain an insulation effect equivalent to four, six or even more inches of rock wool, solely by the use of metallic reflective surfaces. I'he building unit of this invention, described hereinafter, is essentially prefabricated, very compact in form for shipping and storage, and readil installable at very little cost. v

Other objects and advantages of this invention will be apparent to those skilled in the art from a reading of the following specication and from the accompanying drawings showing illustrative embodiments of the invention.

In the drawings (whereinlike members in the different gures represent like parts):

Fig. 1 is a diagrammatic cross-section of an applied building unit embodying this invention.

Fig. 2 is a diagrammatic cross-section of the building unit shown in Fig. 1, collapsed for storage and transportation. g

Fig. 3 is a perspective view of the spreader element of the applied building unit shown in Fig. 1.

Fig. 4 is a diagrammatic cross-section of an applied building unit representing another embodiment of this invention.

Fig. 5 is a fragmentary cross-section of the building unit shown in Fig. 4, collapsed for storage and transportation.

Fig. 6 is a diagrammatic cross-section of an applied building unit representing a further embodiment of this invention.

Fig. 7 is a fragmentary cross-section of the building unit shown in Fig. 6, collapsed for storage and transportation.

Fig. 8 is a cross-section of an applied building unit representing a still further embodiment of the invention.

Fig. 9 is a fragmentary cross-section of the building unit shown in Fig. 8, collapsed for storage and transportation. y

In the drawings, Fig. l shows a rigid buildingt board I, such as gypsum board, ber wall-boad etc. nailed to studs (or beams) 2, 2 by means of nails 3, 3'.. To this rigid board is attached a multiple layer, 4, 5, of either paper (coated on one or both surfaces with a bright metal) or metallic foil, the layers being schematically shown in the drawing as single unbroken lines. Thisy multiple layer is supported by foldable side elements 6, 6 (of paper or equivalent material) the arrangement being similar to a bellows. These sidev elements are attached to the rigiad building board I, at 1, 1' by gluing or stapling, for example. In Fig. 2, the bellows arrangement of the multiple layer and side elements is shown in the collapsed form.

In Fig. 3 is .shown one of the spreader elements 8, vused to expand the bellows arrangement when the unit is to be installed. These elements may be made of sheet iron or other rigid material, and are provided with a hole to receive the nails 3, 3', and with a reduced tip 9. The rigid board has slots II, I I', to permit the spreader elements to slip through, and may be provided with suitable depressions on its outer surface to receive the arms of the spreader elements, so as to make the arms flush with that surface. On insertion of these elements, the tips engage openings I0, I0' (see Fig. 2) `in extensions of the layer 5, thus gripping the multiple layers and spreading them apart, as shown in Fig. 1. The openings I0, IIJ' may, if necessary, be suitably reinforced; and the tip 9 of the spreader element may be detorsally barbed, for retention in these openings. The applied building unit thus provides parallel air cells each bounded by a metallic heat-reiiective surface, and hence producing a wall of high insulating value. (The spreader elements are desirably passed through the rigid board and positioned in the openings I0, I0 before the rigid board is placed against thestuds, thus avoiding fishing for the openings.)

In Fig. 4 is shown the same rigid building board I, to which is attached foldable side elements 6, 6. The middle layer 4 is the same as the corresponding one in Fig. 1. However, in this embodiment of the invention, a sheet I2, of a stiff material, such as corrugated fiber-board or the like, serves as the cuter of the multiple layers. To this sheet I2 may be applied a bright metallic coating on one or both sides. This stiff sheet is made wider than the space between the studs, and the extensions are bent along scored lines, providing side members I3, I4, which serve to spread apart and maintain the bellows arrangement. In Fig. 5, this unit is shown in collapsed form, the scored line for folding being indicatedas I5.

In Fig. 6 is shown a modification of the embodiment shown in Fig. 4. In this (simpler) modification, a sheet I6, of a stili` material, such as corrugated fiber-board or the like, carries the bright metallic coating on one or both sides, the coating being illustrated by the heavy lines I6', I6 and the side members Il, I8, formed by folding extensions of layer I6 along scored lines are attached to the rigid board I by means of hinges, I9, 20, formed of flexible material, for example. Fig. 7 shows one end of this embodiment when in the collapsed cform.

Fig. 8 shows a still further embodiment *of this invention, in which expanded-metal lath 2| (illustrated schematically by a heavy broken line) replaces the rigid building board while retaining all the advantages of this invention. In this embodiment, the expanded metal lath is backed by a paper layer 22, which serves to prevent excess plaster from passing through the metal lath, and

which may also carrya. bright metal coating on the side opposite from the lath. The multiple layers 4, 5 and foldable side elements 6, 6', are the same as those shown in Fig. 1. In this ernbodiment, however, the side elements are provided with extensions 23, 24, which together with the edges of the paper layer 22 are gripped by the metal lath as the latter is folded over and flattened as shown in Figs. 8 and 9, the flattened folds being so spaced as to rest directly on the studs. f

Spreader elements 8 are used here in the same manner as in Fig. 1, the elements being passed through the metal lath to grip and open the bely lows arrangement, and being nailed to the studs.

Fig. 9 shows one end of the embodiment shown Y readily attached to the lathing material in the same bellows arrangementv (the spreading elements being made sufiiciently rigid so as to open up all the layers and hold them permanently in? the expanded form). The spreading elements may be placed at sufliciently frequent i-ntervals along the studs so as to prevent any possible collapsing of the bellows arrangement.

Although the illustrated embodiments of the invention are adapted to provide insulation between one pair of studs only. it should be obvious that the lathing material could be of such size as to extend over two or more inter-stud spaces and have attached thereto separate insulation for each of the interstud spaces.

The invention may be variously otherwise embodied within the scope of the appended claim.

A building unit capable of providing lath and heat insulation on application, comprising lathing material adapted to be fastened to the edges of two consecutive framing members of a structure, a sheet of substantially stii material extending substantially parallel to the lathing material and adapted to t between the two consecutive framing members, side members, spaced and oppositely disposed with respect to each other and coextensive with the sheet and joining the sheet to the lathing material so as to provide a substantially enclosed air space, the
